ABSTRACT
In this study,Reed (phragmites australis) particles and urea formaldehyde(uf) resin were used tor particleboard manulacturing. the properties ot ut bonded reed particle boards were relatively lower then those of commercial particleboard.the purpose of this study was to improve bondability by pf resin. In this experiment, phenol formaldehyde(pf) was used to replace 5 and 10% of uf adhesive. The properties of the resulting mixed adhesive products were then evaluated and compared with particleboard bond with only uf. Properties evaluated were modulus of rupture(MOR) Internal bond(IB),thickness swelling(TS) and water absorption. The results showed that replacement of uf with pf improved the mechanical and physical properties of particleboard. The best condition according to Iranian standard obtained in 5% replacement and 190BC press temperature and 6 min press time.
